前回より、大雑把なエリアを決定し、今回はSUUMOからの物件をスクレイピングします。目的地は藤沢周辺です。

最初に総ページ数を見つけます：

number_of_pages = bs.find('ol', {'class': 'pagination-parts'}).find_all('li')[-1].find('a').get_text()  # 找出租房物件总页数
そして、一ページの情報採集、ループに入れて、出力します。
一個一個のページが終わったら、excelに更新して出力します。万が一ネット通信エラーとか、サバーに禁止されるとかの際に、取った情報を確保します。
余計な情報を略すため、藤沢と辻堂いずれかの情報があれば、別のファイル保存します。（Boolマスクを作る）
# 选出必定在藤泽和辻堂駅附近的房屋
new_df = df[(df['station_1'] == '藤沢駅') | (df['station_1'] == '辻堂駅') | (df['station_2'] == '藤沢駅') | (
df['station_2'] == '辻堂駅') | (df['station_3'] == '藤沢駅') | (df['station_3'] == '辻堂駅')]
